Exponential family mixed membership models for soft?clustering of multivariate data

Exponential family mixed membership models for soft?clustering of multivariate data

... The general case of mixed membership models, where quite general component distributions were allowed, has been outlined by Erosheva et al. (2004), however, details of how inference is to be performed are omitted; a ...

Estimation of P(X>Y) for the Positive Exponential Family of Distributions

Estimation of P(X>Y) for the Positive Exponential Family of Distributions

... Constantine et al. (1986) derived UMVUE and MLE of P when X and Y follow gamma distributions with shape parameters to be integer-valued. Huang et al. (2012) generalized these results for the case when shape parameters ...

Explaining and Generalizing Skip Gram through Exponential Family Principal Component Analysis

Explaining and Generalizing Skip Gram through Exponential Family Principal Component Analysis

... We have presented an interpretation of the skip- gram model as exponential family principal com- ponents analysis—a form of matrix factorization— and, thus, related it to an older strain of work. Building ...

Parameter Uncertainty in Exponential Family Tail Estimation

Parameter Uncertainty in Exponential Family Tail Estimation

... The analytically tractable examples of section 2 show that tail estimates may be very biased. In order to be able to treat more general cases, we develop in this section asymptotic formulas that can be used to ...
